Embodiment Construction

[0071] The present invention is mainly aimed at the optimization of the encryption data processing of the user plane of the LTE base station, and is applicable to but not limited to the LTE base station. This solution is also applicable to other design methods for cooperatively processing data between the CPU and the functional chip in the embedded system. This method can meet the needs of high-speed encrypted data transmission in the construction of wireless communication base stations, and effectively reduce the occupation of CPU resources. A series of cutting-edge technologies such as offloading can effectively reduce CPU resource scheduling and improve processing performance.

[0072] The technical solution of the present invention will be described in detail below in conjunction with the drawings and embodiments.

[0073] The embodiment of the present invention provides a method for optimizing the performance of encryption and decryption data of the user plane of an LTE b...

Abstract

The present invention proposes a user plane data processing method in which an IPSec encryption card and a CPU are coordinated, and a CPU, an IPSec encryption card, and an exchange chip for data shunting are provided; Learn the MAC address, perform IKE negotiation and configure it in the encryption card, configure the ACL rule on the switch chip, filter the message whose IP protocol field is ESP on the interface connecting the switch chip and the PHY device, and force forward it to the encryption card; During the round-trip process, the encryption card processes the message encryption and decryption. The technical scheme of the invention can reduce resource consumption and improve performance and versatility in the process of encrypting and decrypting data on the user plane of the base station. Because the separation of protocol and data processing is realized, the flexibility of the protocol is guaranteed, and the performance is improved, and the IP / MAC address conflict between the CPU and the IPSec encryption card is avoided at the same time.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to providing an IPSec encryption card and a CPU cooperative work method for confidential and safe communication. Background technique [0002] With the advancement of wireless communication technology and the continuous upgrading and transformation of wireless network equipment, the requirements for user plane data processing of LTE (3GPP long-term evolution technology) base stations are getting higher and higher. On the other hand, network threats are becoming more and more serious, and user data carried by LTE base stations is becoming more and more important, which requires that user data be encrypted and transmitted in ciphertext. Internet Protocol Security (IPSec) is an open standard framework for ensuring confidential and secure communications over Internet Protocol (IP) networks through the use of encrypted security services. At present, the relatively mature encryption m...
